TrackingService 建構函式

定義

命名空間:

System.Workflow.Runtime.Tracking

組件:

System.Workflow.Runtime.dll

在衍生類別中實作時，初始化 TrackingService 類別的新執行個體。

protected:
 TrackingService();

protected TrackingService ();

Protected Sub New ()

範例

下列範例示範如何建立 TerminationTrackingService 物件的新執行個體，這個物件的型別衍生自 TrackingService。 這個範例來自＜終止追蹤服務 SDK＞範例。 如需詳細資訊，請參閱 終止追蹤服務範例。

using (WorkflowRuntime workflowRuntime = new WorkflowRuntime())
{
    AutoResetEvent waitHandle = new AutoResetEvent(false);
    NameValueCollection parameters = new NameValueCollection();
    parameters.Add("EventSource", eventSource);

    workflowRuntime.AddService(new TerminationTrackingService(parameters));
    workflowRuntime.WorkflowCompleted += delegate(object sender, WorkflowCompletedEventArgs e) { waitHandle.Set(); };
    workflowRuntime.WorkflowTerminated += delegate(object sender, WorkflowTerminatedEventArgs e)
    {
        Console.WriteLine(e.Exception.Message);
        waitHandle.Set();
    };

    WorkflowInstance instance = workflowRuntime.CreateWorkflow(typeof(SampleWorkflow));
    instance.Start();

    waitHandle.WaitOne();
}

Using workflowRuntime As New WorkflowRuntime()

    Dim waitHandle As New AutoResetEvent(False)
    Dim parameters As New NameValueCollection()
    parameters.Add("EventSource", eventSource)

    workflowRuntime.AddService(New TerminationTrackingService(parameters))
    AddHandler workflowRuntime.WorkflowCompleted, AddressOf WorkflowRuntime_WorkflowCompleted
    AddHandler workflowRuntime.WorkflowTerminated, AddressOf WorkflowRuntime_WorkflowTerminated

    Dim instance As WorkflowInstance = workflowRuntime.CreateWorkflow(GetType(SampleWorkflow))
    instance.Start()

    waitHandle.WaitOne()
End Using
